Cloudflare Stream

A minimalistic node.js package for easily uploading videos to Cloudflare Stream.

Getting Started

Let's start off by installing the package via NPM.

npm i cloudflare-stream

Once you've done that, you're going to want to create an instance of a CloudflareStream with your credentials.

import { CloudflareStream } from 'cloudflare-stream';
 
const uploader = new CloudflareStream({
  email: '[e-mail]', // cloudflare email address
  key: 'c23864bc3ada9bf9c937810f62bb69a4e90b0' // cloudflare api key
});

Now that you've made an instance, you're going to want to upload your video to your zone. Let's create an upload with your upload options.

const upload = uploader.upload({
  zone: 'ca4239cdd6a52cec1e916a6cd0e2f629', // cloudflare zone id
  path: './videos/demo-video.mp4' // path to video on filesystem
});

The upload method returns an EventEmitter which has three events (progress, success, error).

Let's create some logs from your upload events.

upload.on('progress', (progress) => {
  console.log(`${progress.precentage} of upload completed (${progress.uploaded} bytes / ${progress.total} bytes)`);
});
 
upload.on('error', (error) => {
  console.log('An error has occurred', error);
});
 
upload.on('success', (response) => {
  console.log(response);
});

API Documentation

CloudflareStream

class CloudflareStream {
 
  constructor(credentials: CloudflareCredentials);
 
  upload(uploadOptions: CloudflareUpload);
 
}

constructor(credentials)

credentials

type CloudflareCredentials {
  email,
  key,
  zone?
}

credentials.email

An email is always required, it should be the email address which you use to sign in with Cloudflare.

credentials.key

A key is always required, it should be the API Key which matches the email address which you use to sign in with Cloudflare.

credentials.zone

If a zone is not set in the uploadOptions of an instance method, then a zone is required in the credentials.

A zone must be a valid Cloudflare DNS Zone which is accessable using the specified email address and API key.

upload(uploadOptions)

Returns an EventEmitter with three events (progress, success, error).

uploadOptions

type CloudflareUpload {
  zone?,
  path?,
  buffer?
}

uploadOptions.zone

If a zone has not been set in the constructor, then a zone is required in the uploadOptions.

A zone must be a valid Cloudflare DNS Zone which is accessable using the specified email address and API key.

If a zone has already been set in the constructor, this value will overwrite it.

uploadOptions.path

If a buffer has not been set in the uploadOptions, then a path is required.

A path must be a string pointing to a video file on the local filesystem.

It can be either an absolute path or a path relative to the node.js process (process.cwd()).

uploadOptions.zone

If a path has not been set in the uploadOptions, then a buffer is required.

A buffer must be a valid node.js Buffer.
